Linear Axis Label Format - 0

Hi,

I have a chart which has a linear axis and with a range of -150 to 150. As soon as I zoom the label for 0 is displayed in scientific notation (see attached image). Is there a way I can stop this? I would prefer to not have to set a format string on the axis as I would like the labels to show more decimal places as the user zooms in to view the data in more detail.

Thanks,

Steven

Disable Drop On RadPane

Hi,

I have a RadScheduleView and a Listbox in a UserControl that I am dragging appointments between which works great.

My issue is that my application uses a RadDocking control with a RadPane docked on the left with the UserControl inside a RadDocumentPane on the right. When I am dragging an appointment and I move outside of the UserControl and onto the RadPane it is showing that it will accept the Drop of the appointment which it shouldn't. I have tried setting AllowDrop = false on the RadPane but this does not change anything.

Any ideas?

Thanks
Anthony

Custom Tool with square selection

Hi,

I need to implement a custom tool that is very similar to the crop tool in the user experience. I mean the user has to activate the tool, draw a square across the image, resize and move if necessary and then trigger a custom functionality instead of cropping.

Is it possibile to perform it by overriding the crop tool or it needs to create a new ITool from the scratch? How can I implement that two steps process (Selection/adjustment then action) whithin a custom tool? How can I manage to draw the square like in the crop tool?

Thank you very much for your responses

My warmest regards

Databinding difficulty with color

Hi,
I seem to be unable to get the databinding to work so that, for example, the background colour of a grid cell is set to the colour property of a business object. Please can someone take a look and show me the error of my ways?

ORM version 2013.2.702.1
RadControls for WPF version 2013.2.724.40

In summary, I am getting a list back from the database using a stored procedure mapped to a domain method. I have also added a partial class and a transient property to the result item in my ORM library. This transient property is a System.Windows.Media.Color and the values are stored in an XML file that are merged with the database result by my view model prior to the view being presented.

In my attempt to understand why the colour is not set, I am showing the ToString result in the cell so I know the colour value is present, however, the colour of the cell remains white.

Here's my ORM partial class:

using System;

using System.Linq;

using System.Windows.Media;

namespace xyz

{

public partial class DBLISTitem

{

[Telerik.OpenAccess.Transient]

private Color _patternColour;

public Color PatternColour

{

get

{

return _patternColour;

}

set

{

_patternColour = value;

}

Here's the XAML cut down for brevity:

<UserControl x:Class="..."

>

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding ColName}" Header="Col1" Width="*" />

<telerik:GridViewDataColumn Header="Colour" Width="150">

<telerik:GridViewDataColumn.CellTemplate>

<DataTemplate>

<TextBlock Text="{Binding Path=PatternColour}" Background="{Binding Path=PatternColour, Converter={StaticResource ColorToBrushConverter}}" Margin="0" />

</DataTemplate>

</telerik:GridViewDataColumn.CellTemplate>

</telerik:GridViewDataColumn>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

</Grid>

</UserControl>

I've attached a sample of the output view.

I've since worked on a very simple test project to try to reproduce the problem but I cannot. The test app works. I changed the cell template in the problem app to match the working test app as follows:

<telerik:GridViewDataColumn.CellTemplate>

<DataTemplate>

<TextBlock Text="{Binding Path=HatchPatternColour}" Margin="0">

<TextBlock.Background>

<SolidColorBrush Color="{Binding Path=HatchPatternColour}" />

</TextBlock.Background>

</TextBlock>

</DataTemplate>

</telerik:GridViewDataColumn.CellTemplate>

This made no difference. The backgound color remains white.

Further to this, I've increased the trace level to high and get this output for the SolidColorBrush binding:

Doesn't this show that it has found the Color property?

Any suggestions please?

LogIn Control

Hello.
I'm a beginner.
I think it's kind of difficult to make program related to Log-in stuff to me.
Do you have a plan to support Wpf Login Control.

Using RadCartesianChart events

Hi,

I have a chart like the one in the attached image, this is the code:

<telerik:RadCartesianChart Name="CartesianChartDemo" Margin="10">

<telerik:RadCartesianChart.Behaviors>

<telerik:ChartPanAndZoomBehavior PanMode="Both" ZoomMode="Both"/>

</telerik:RadCartesianChart.Behaviors>

</telerik:RadCartesianChart>

CartesianChartDemo.VerticalAxis = new LinearAxis();

CartesianChartDemo.HorizontalAxis = new CategoricalAxis();

CartesianChartDemo.Grid = new CartesianChartGrid() { MajorLinesVisibility = GridLineVisibility.XY };

DataTable dtAlloys = new DataTable("DATA");

dtAlloys.Columns.Add(new DataColumn("Name", typeof(string)));

dtAlloys.Columns.Add(new DataColumn("Value1", typeof(double)));

dtAlloys.Columns.Add(new DataColumn("Value2", typeof(double)));

dtAlloys.Rows.Add(new object[] { "Value1", 70, 30 });

dtAlloys.Rows.Add(new object[] { "Value2", 15, 85 });

dtAlloys.Rows.Add(new object[] { "Value3", 50, 50 });

BarSeries barSer = new BarSeries();

barSer.ShowLabels = true;

barSer.CombineMode = ChartSeriesCombineMode.Stack100;

BarSeries barSer2 = new BarSeries();

barSer2.ShowLabels = true;

barSer2.CombineMode = ChartSeriesCombineMode.Stack100;

foreach (DataRow drAlloy in dtAlloys.Rows)

{

barSer.DataPoints.Add(new CategoricalDataPoint() { Category = drAlloy["Name"], Label = string.Format("{0:N}", drAlloy["Value1"]), Value = double.Parse(drAlloy["Value1"].ToString()) });

barSer2.DataPoints.Add(new CategoricalDataPoint() { Category = drAlloy["Name"], Label = string.Format("{0:N}", drAlloy["Value2"]), Value = double.Parse(drAlloy["Value2"].ToString()) });

}

CartesianChartDemo.Series.Clear();

CartesianChartDemo.Series.Add(barSer);

CartesianChartDemo.Series.Add(barSer2);

I am trying to use the MouseDown event to do something like show an alert with bar info or open a new window and pass it data from that bar that I am clicking.

How can I obtain the data of the bar that I am clicking?

It is ok to use that event or should I use another one?

Thanks,

Alberto

Paste issues with GridView

I'm trying to implement paste functionality into my GridView, but have run into 2 issues.

First, even if the Grid is set with SelectionUnit="FullRow" SelectionMode="Single", after a paste occurs the top row where the data was pasted remains selected. I can then select another row, ending up with multiple-rows selected. Subsequent pastes start at the top-most selected row, even if it's not the most recently selected row. Therefore, in addition to a very strange display (with multiple rows selected and no apparent way to unselect them), you can never paste data into rows below where you have previously pasted data.

The second issue is that the InsertNewRows value of GridViewClipboardPasteMode no longer appears to be present, such that pasting data when not enough rows exist to accommodate truncates the paste.

For reference, the options I'm using are:

       <telerik:RadGridView Grid.Row="0"  x:Name="HistoricalGridView" AutoGenerateColumns="False" ItemsSource="{Binding Path=HistoricalData}" 
                                 IsFilteringAllowed="False" ShowGroupPanel="False" CanUserSortColumns="False" 
                              ClipboardPasteMode="OverwriteWithEmptyValues,Cells" SelectionUnit="FullRow" SelectionMode="Single" >

Thanks for your help on these.
